RUBBER. HEEL.

Application filed. April 10, 1924. Serial N'o. 705,493.

to provide a novel form of rubber heel comprised of a number ofsections, whereby renewal of a worn section is possible without renewalof the whole heel, it being a well known fact that heels do not wearevenly throughout the entire area thereof.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawing, and to the appended claims in which thevarious novel features of the invention are more particularly set forth.

Fig. l of the drawings is an underside face view of my improved heel.

Fig. 2 is a transverse vertical sectional view taken on the line 22 ofFig. 1.

In constructing my improved rubber heel I provide a number of concentricsections or members which jointly form the heel, three of these sectionsbeing here shown and numbered respectively 10, 11 and 12. Of thesesections, the outer and intermediate sections 10 and 11 respectively arein the forms of rings or annuli, while the inner section is in the formof a circular block having an opening through the centre thereof toreceive a fastening screw 13. The inner section is directly engaged andheld by the head 13 of the screw, while the intermediate section 11 isformed with an inwardly projecting lower portion or flange 14 whichengages in an undercut peripheral recess in the inner section. therebypreventing displacement of the said intermediate section.

As will be understood, the outer section 10 is the one which is subjectto the greatest wear and I have therefore provided a means for holdingthis outer section in place which permits of its removal and replacementwithout removing the other sections, or completely withdrawing the screw13, the latter serving to tighten the said means. As here shown arelatively thin circular plate 16 is fixed on the usual leather element17 f rm g the upp r part f h h l f t boot or shoe, and is provided atits periphery with a series of downwardly and outwardly projectingresilient prongs 18 which preferably taper from their roots toward theirtips, the extreme tips being bent backward at substantially right anglesto the bodies of the tongues as indicated. at '18, the bodies of theseprongs preferably extending at an angle of forty-five degrees to theplate 16. The tips 18 of the prongs are adapted to engage the upperwalls of a number of recesses 20 out in the inner face of the said outersection 10, while other recesses 21 are formed in the outer wall of theintermediate section 11 to accommodate these prongs when the latter, arewithdrawn from the recesses 20.

Fitting upward against the plate 16 is a thicker disk 24 having abeveled edge which fits against the prongs 18 and which is adapted, whenthe screw 13 is tightened, to move said prongs outward and upward toengage in the recesses 20 and grip the upper wall thereof, the screw 13being enlarged at its lower portion to provide a shoulder which bearsagainst this disk, the screw passing freely through the disk. I

have here shown the socket for the screw in the form of an extension 16from the plate 16 embedded in the leather heel element 17. The inner andintermediate sections are of somewhat less thickness than the outersection and bear at their upper faces on the disk 24, while the outersection bears at its upper face on the leather heel element 17.

If it is desired to remove the outer section the screw 13 is loosenedslightly, allowing the prongs 18 to move inwardly and thereby freeingtheir tips from the recesses 20 in the said outer section, which canthen be withdrawn, and a new one placed in position on the heel, afterwhich the screw is tightened, causing the disk 24 to move up against theplate 16 and force the prongs outward to grip the new section and holdit in place. If the intermediate section also needs replacing the screwis completely loosened, the replacing of the intermediate section beingnecessitated at rarer intervals than the replacing of the outer section.Furthermore, the construction permits of the outer section beingadjusted circularly as desired to turn the worn rear parts toward thefront of the heel.

Having thus described my invention what I claim as new and desire toprotect by Letters Patent of the United States is as follows:

1. In a heel, a top heel element, a rubber heel made up of a number ofconcentrically arranged sections comprising an outer section, andintermediate section and an inner section, a fastening screw passedthrough said inner section and engaged with the said top heel element, aplate fixed to the said top heel element and formed with downwardly andoutwardly projecting prongs, and a disk adapted to be forced by saidscrew against the said prongs to move the latter into locking engagementwith the said outer section.

2. In a heel, a. top heel element, a rubber heelmade. up of a number ofconcentrically arranged sections comprising an outer section, andintermediate section and an inner section, a fastening screw passedthrough said inner section and engaged with the said top heel element, aplate fixed to the said top heel element and formed with downwardly andoutwardly projecting prongs,

and a disk adapted to be forced by said screw against the said prongs tomove the latter into locking engagement with the said outer section,said outer section having a number of recesses formed in the inner facethereof to receive the said prongs.

In testimony whereof I have ailixed my signature.
